This paper considers the case of partially observed demand in the context of a multi-period inventory problem with lost … sales. Demand in a period is observed if it is less than the inventory level in that period and the leftover inventory is …. These observations are used to update the demand distributions over time. The state of the resulting dynamic program …

service level goals. The proposed model uses the expected demand and substitution probabilities between products as inputs and … has been used to analyze the effects of demand variability on profitability under service level constraint. The results of … correlations in demand leads to significantly inefficient assortments …

theory, predicting that greater risk reduces contestants' incentives to exert effort. Moreover, the equilibrium prize spread … ambiguity adversely affects business unit managers' effort choices, project risk can partly offset the adverse effect of … is shown to decrease with ambiguity and increase with project risk. Finally, while greater project risk is unequivocally …

We consider a multi-product newsvendor under the law-invariant coherent risk measures. We first establish a few … fundamental properties of the model regarding the convexity of the problem, the symmetry of the solution and the impact of risk … aversion. Specifically, we show that for identical products with independent demands, increased risk aversion leads to …

, by incorporating the conditional value at risk (CVaR), the risk induced by uncertain demand is explicitly considered. The … relocatable modular capacities. A robust supply network configuration must be determined based on uncertain demand. Furthermore … derived supply network configuration is robust and stable in the presence of uncertain demand …

Capacity expansion is the process of providing new facilities over time to meet rising demand. A general mathematical … model of this process is presented, incorporating uncertain future demand (including the possibility of 'surprises'), non … expansion project. Optimization is studied by methods of stochastic control theory. Numerical algorithms are presented which …

reduction in some countries have not been the accelerator sufficient for the global recovery. The general level of demand is low … demand, as well as the options available for removal of those causes and revitalization of the effects. One of the main … causes of decrease in demand in a long run is the asymmetrical distribution of income which has led to a reduction in …
